Natural wetlands are flat and often have deep, nutrient rich soil with an abundant water supply. These conditions are ideal to agriculture

The main reason why the wetland habitats are often favored for transforming to new farmland is that the natural wetlands are flat and often hold deep, nutrient-rich loam with plentiful water availability. In other words, the natural wetlands possess sufficient water supply and soil with rich nutrient etc. which presents a perfect condition for farming. Thus, they prefer converting to new agricultural land.

The mass of a single atom of carbon can be found by dividing the atomic mass (12.01 g) by 6.022 mc024-1.jpg 1023.

marin [14]

The mass of one atom of carbon in the correct number of significant figures is 1.99×10-²³. There are four significant figures each in both the atomic mass of carbon (12.01 g) and Avogadro's number, so the answer must also have 4 significant figures. The operation is shown below:

12.01 / (6.022x10²³) = 1.994x10₋²³

There are 100 cats in a population that follows hardy-weinberg conditions. 4 cats display a recessive white coat color. how many

mr Goodwill [35]

We know that Hardy-Weinberg conditions include the following equations:

$p^{2}+2pq+ q^{2}=1$

where $p+q=1$

And where p = dominant, and q = recessive; this means that $p^{2}$ is equal to the homozygous dominant, $2pq$ is the heterozygous, and $q^{2}$ is the homozygous recessive .

So we have 100 total cats, with 4 having the recessive white coat color. That means we have a ratio of $\frac{4}{100}$ or 0.04. Let that equal our $q^{2}$ value.

So when we solve for q, we get:

$q^{2}=0.04$

$q=\sqrt{0.04} =0.2$

Now that we have our q value, we can use the other equation to find p:

$p+q=1$

$p+0.2=1$

$p=0.8$

So then we can solve for our heterozygous population:

$2pq=2(0.8)(0.2)=0.32$

This is the ratio of the population. So we then multiply this number by 100 to get the number of cats that are heterozygous:

$0.32*100=32cats$

So now we know that there are 32 heterozygous cats in the population.
